Right, with you lot being 'smart', I've tried to find something really obscure!

About the size of a pocket watch, any ideas?

I watched part of A Sound of Thunder last night. We're all doomed unless he puts it back where he found it.

I think it's a circular slide rule, and quite an expensive one, and also with a specific application, because of its build quality may be military hence application might be bomb aiming?

when I was 13 (1974) my sister bought me a circular slide rule. It was a curiosity and not much practical use. I sold it on ebay last year for about £7 and bought a conventional one with the money. I loved the link to online slide rules on CR4 quite recently.

The accuracy on a 3.n " one was about the same as a 10" slide rule but could fit into your shirt pocket. very handy'

It is an instrument for measuring distances on a plan. I think it had a name as well.

Sorry!! It has a log scale - so it might be the readout on a planimeter. (mechanical area integrator)

It's definately a circular slide rule. A Russian KL-1, in fact. Didn't they stop making those in the mid 60's? Or are they still cranking them out?

Of course I'm spot on. Didn't I mention that I'm completely brilliant? Anyway, go ahead and jot that down somewhere for future reference.

I'm sure that we would want nothing bad said about Mr Mosley, what with him being a lawyer and a bit touchy.

Well done. This one is a bit of a stumper.

I'm going to go way out on a limb and say that they're to suspend electrical filiments. Possibly in a very large and powerful light bulb or one heck of a vacuum tube.

Either that or some sort of a very devilish brassiere clasp.

It does look a bit like a high powered lamp filament doesn't it?

Can you give us a clue as to how big the picture is??

If there are weights hung on each wire at the bottom, it could be a mechanical filter.

They could be part of a suspension system, or part of vibration deflection or dampening system. Or both.

Could they be part of a musical instrument?

They emit photons and heat as a result of resistance to electrical current passing through them.

My first thought was 'high intensity discharge lamp filament suspension', but the resemblance is only superficial. The search continues...

I think it's a flashbulb. Yes?

Despite being completely brilliant, I can't believe I got that spring one. Tricky. I began to doubt my guess and instead considered all sorts of improbable things!

It has been said there is a fine line between genius and insanity. As one of our Member's tag line says: "Insanity takes its toll - please have exact change." Too many 'guests' to keep track of here...

Either a 1950's-vintage camera flashbulb, or a glass paperweight. W/o scale, it's difficult to distinguish...

I always wondered what one of Del's hairballs looked like!

If it's not a bulb from a strobe or spotlight, it's a android's testicle.

I would have said its a hygrometer with the circular scales showing dewpoint RH% etc...

A circular sliderule needs access to the scales to rotate them doesn't it?
